Shear thickening fluids are dense suspensions that exhibit a striking increase in viscosity when subjected to applied stress or shear rate. At rest or under gentle flow these materials behave like low ...

From ketchup to quicksand, non-Newtonian fluids have long fascinated and puzzled scientists. Unlike ordinary fluids, their flow properties change depending on how much force is applied, but the ...

If you’ve ever whacked the bottom of a ketchup bottle to get that tasty tomato goop flowing, you’ve put some serious physics to work. Ketchup is a non-Newtonian fluid. So are toothpaste, yogurt, ...

For the first time, researchers have been able capture images providing unprecedented details of how particles behave in a liquid suspension when the phenomenon known as shear thickening takes place.

Microorganisms navigate complex environments by generating local fluid flows through flagellar rotation, ciliary beating or body undulations. In many natural and host-associated habitats, the ...

What is viscosity: It’s the measure of a fluid’s resistance to flow—low in water, high in honey—and it shapes how substances move and interact. Surprising behaviors: Some fluids change viscosity under ...

Ahh, summer at the beach! The sun on your face, sand between your toes, an ice cream in your hand. For scientists young and old, a trip to the beach is also a perfect opportunity to explore the ...
